I have 8 pin relay...TOYO TY502-DC5V
I can't make out the connections....
This is the circuit I'm working on and I have no Idea bout the relay connection please help me...

 

While your topic is related to the original thread in that you're both talking about relays, what you've done is "hijack" a topic, which is frowned upon around here, as it causes confusion. A moderator will soon move your request to it's own thread.

Relays come in many configurations. I couldn't seem to locate a datasheet for your particular relay, but all is not lost.

From the "DC5V" suffix, it appears that the relay's coil is rated for 5V DC.

Since your relay has 8 pins, one probable configuration would be double-pole, double-throw; each double-throw switch taking 3 pins. This leaves two pins for the relay's coil.

Do you have an image of your relay that you can post?

Are the pins in a circle, or in two rows, evenly spaced, or in two rows, three together and two off by themselves? Or do they resemble a square?

Do one of the pins have a different color insulator at the body? (those usually mark one of the coil connections)

Do you have a multimeter or DMM?
